How the 35C3 presale works

Presale in two phases

As the available tickets for 35C3 are limited and likely to be sold out, the presale will take place in two phases, similar to last year. The goal of this approach is to enable the participants who created the unique setting of last year's Chaos Communication Congress to get a ticket, while at the same time keeping the community open to new people.

In Phase 1, we invite the people who are part of the overall Chaos community, as well as last year's most active angels, since they are the people who made 34C3 as brilliant as it was. In phase 2, we open the presale to everybody, so that people new to our communities can also join us.

The number of tickets sold in the first phase is limited despite the replicating tokens to ensure that there will be enough tickets available in the second phase.

Phase 1

In Phase 1, only people with a voucher can buy a ticket. Note that there is a pool of tickets for this phase and most vouchers do not guarantee a ticket. This phase will run only as long as there are tickets left in the allocated pool but will end on November 7th the latest.

During this phase, some vouchers will create new vouchers after they have been redeemed and the order has been paid for. If your voucher replicates, we will ask you for an email address to which we should send the new voucher. Please note that we do not send vouchers out immediately after confirming your payment, but in regular batches.

Below this timeline, you can find more information on how vouchers are distributed.

Phase 2

In Phase 2, we will sell tickets in three batches - the dates will be announced at least two weeks in advance on events.ccc.de. During Phase 2, original angel vouchers will still work until November 20th, but they will not spawn any new vouchers. All other vouchers will not be accepted anymore.

In this phase, everyone can buy a ticket on a first come first serve basis. Make sure you pay your ticket in time, otherwise we might reassign it to someone else.

Vouchers types

There are two primary types of vouchers that we distribute. The voucher codes are prefixed by their type as can be seen in the table below.

Angel vouchers

Everyone who helped to create last year's congress and worked 12 or more hours of shifts has received an angel voucher via email at the start of Phase 1. This voucher guarantees a ticket until November 20th.

If you redeem your angel voucher within phase 1, you can tell us an email address, and we'll send another voucher to that address about a day after your payment has been processed - if there are still tickets left in Phase 1. This new voucher does not guarantee a ticket and can only be redeemed as long as there are still tickets in the pool for phase 1. It also does not replicate further.

If you have been an angel last year, having worked at least 12 hours of shifts, and you have not received a voucher code yet, please email us as soon as possible at 35c3-tickets [at] cccv [dot] de with your email address and username in the Engelsystem.

Chaos vouchers

We will send out a set of vouchers to the local CCC groups (Erfas and Chaostreffs) as well as related groups, congress crews, and major assemblies. These vouchers are only valid until phase 1 is over (when the ticket pool of phase 1 is empty). Therefore, they do not guarantee a ticket.

If you redeem a Chaos voucher, you can tell us an email address, and we'll send another voucher to that address about a day after your payment has been processed - if there are still tickets left in Phase 1. This new voucher does not guarantee a ticket and also replicates further recursively.

If you are part of a group (local CCC group, hackerspace from all over the world, etc.) that has not received any vouchers yet and you think you should get a voucher, please email us as soon as possible at 35c3-tickets [at] cccv [dot] de. It does not hurt to ask, and if we forgot you or agree that you should receive vouchers, we can only help you if we know it early on.
